During his years as a U.S. Senator and now as Attorney General, Jeff Sessions has repeatedly stated that marijuana is only "slightly less awful than heroin," a claim that is rebuked by scientific experts. His office recently revoked the federal Cole Memo, under which states that legalized marijuana were allowed to sell pot under the strict conditions laid out in the memo.

On January 4, KING 5 interviewed Dr. Dennis Donovan, Director of the UW's Alcohol and Drug Abuse Institute about the comparative risks of marijuana and heroin, and the fear that legalization will lead to increased use of marijuana.
